AS12350 peers with these other Autonomous Systems.

Peering is a direct, often free, traffic exchange between Autonomous Systems (ASNs). They share routes only to their own networks and customers, making connections faster and cheaper for that specific traffic, without providing full internet access to each other.

Upstreams of AS12350

1 upstreams

AS34177

AS12350 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS12350 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS12350

4 downstreams

AS3334 AS205393 AS208381 AS215825

AS12350 provides internet connectivity to these downstream Autonomous Systems.

A downstream is a customer Autonomous System that pays another AS (its provider) for internet access. The provider AS carries the downstream's traffic and makes its network reachable.
